So cool. I mean, Linneaus first wrote about them. They have great fuzzy flower balls (pink fibers with orange tips) but the leaves actually shut when you touch them.
Bit hard to get great video given wind and, well, my competencies. But here’s a shot.
Link to a movie of the leaves closing when I hassle them [external link because this is fun but ain’t no way I’m paying $96 for a year of premium for one movie]: http://motion.cps.utexas.edu/wp-content/uploads/2020/04/IMG_5027.mov
Found right out by the front gate. I have seen these around there on and off for years.
